    Abstract: A valve system for the overhead valve type four-cycle engine disposing the intake and exhaust valves substantially symmetrically to each other with respect to the cylinder center line, wherein the valve stems are so tilted in the cylinder head that the valve bodies are in juxtaposition close to the cylinder center line. Guide cams are disposed around the circumferential surface of the crank shaft, respectively return back to the same starting point while making two turns, and respectively have one projection in the course of the turn, for driving the intake and exhaust valves. Between the guide cams and the respective intake and exhaust valve, a sliding piece, push rod and rocker arm are provided, and the projection on each of aforesaid cam is designed to be placed at such a position as to engage with the sliding piece to the opening timing of the intake and exhaust valves.

    Abstract: An internal combustion engine comprising a cylinder having an exhaust port, a piston movable within the cylinder in a compression stroke, an exhaust valve for opening and closing the exhaust port, and a cam shaft including a cam member for selectively moving the exhaust valve between open and closed positions. The cam shaft includes a radially-extending opening positioned partially through the cam shaft. The engine further includes an auxiliary cam slidably positioned within the opening and movable radially between an operative position, where the exhaust valve is held open during the compression stroke, and an inoperative position. The auxiliary cam extends only partially through the cam shaft. The engine can further include an auxiliary shaft movably (e.g., rotatably) mounted within the cam shaft and adapted to move the auxiliary cam between the operative position and the inoperative position.

    Abstract: Conventional lifter assemblies are relatively expensive to manufacture and generally extend laterally significantly beyond the ends of the roller surface thereof. As a result, fuel pumps utilizing such conventional assemblies must be spaced relatively far apart so that a sufficient roller surface is provided to contact a camshaft. Further, such assemblies are generally relatively heavy, leading to high inertial changes on reciprocation thereof. The ends (42,43 or 142,143) of the roller (14 or 114) are adjacent the inner diameter of the sleeve (28 or 128), whereby the roller (14 or 114) of the resulting lifter assembly (10) extends nearly the full width thereof. A roller holder (30 or 130) fits within one end (32 or 132) of the sleeve (28 or 128) and holds the roller (14 or 114) in a cavity (36 or 136) therein.

    Abstract: A plunger assembly employed in a fuel injection pump terminates at its lower end at a roller bearing which engages a cam lobe of an engine driven cam shaft. A spring clip has a ring portion and a pair of leg portions extending downwardly therefrom to engage opposite ends of the roller bearing to restrain axial displacement thereof.
